CRXJS is a set of Vite and Rollup plugins for building cross-browser extensions with native hot module replacement and zero-config setup. It supports Manifest V3 via the Vite plugin and Manifest V2 via the Rollup plugin, with automatic handling of static assets and web-accessible resources.

Use cases

  • build a chrome extension with vite
  • add hot module replacement to extension development
  • scaffold a browser extension project with react or vue
  • develop content scripts with instant reload
  • migrate a chrome extension to manifest v3
  • auto-generate web_accessible_resources for an extension

When to choose

  • you are building a Chrome or cross-browser extension with Vite
  • you want HMR that works with content scripts and preserves extension state
  • you want zero-config setup with intelligent defaults
  • you need Manifest V3 support with TypeScript

When to avoid

  • you need Manifest V2 support and prefer the newer Vite plugin (MV2 requires the separate Rollup plugin)
  • you are not building a browser extension
  • you need a build tool without a Node.js/Vite ecosystem
